Perhaps you've gone through this sensation before. Painful urination can occur for a number of different causes, some of which are mentioned on this page. Endometriosis is one of those possibilities. Please keep in mind that since this website is focused on endometriosis symptoms, the information on this page may be more related to painful urination that occurs in women rather than in men. However, many of the issues related to it (such as causes) can occur in both, so there is some overlap.
Other symptoms may also be present when there is painful urination. In many cases, these can vary significantly based upon the underlying medical reason. On a somewhat related note: the term "dysuria" is sometimes used to describe this type of pain, however, it can also refer to difficulty urinating.
Not all cases of painful urination are caused by endometriosis. In fact, it is most commonly brought on due to a urinary tract infection (sometimes simply called at UTI). There are many other reasons, though, including the following as some of the possibilities:
Certain medications (side effect)
Low blood pressure
Sexually transmitted diseases
There are various methods that may be used to attempt to diagnose particular underlying conditions that can cause dysuria. If you are feeling this sensation, then you may consider visiting a doctor or other professional in the medical field in order to get recommendations for particular tests, exams, etc., that might be used. Some of the medical issues that can lead to painful urination are serious -- but on the other hand, simply having the sensation doesn't mean that it is one of those more serious issues. Look for a proper medical diagnosis rather than assuming that a self-diagnosis is correct.
As with the diagnostic process, treatment in particular cases of painful urination may vary. There are many underlying causes, and the medical reason for the sensation plays a major role in which type of treatment is used. Please get professional advice in this area.
